So, im sure a lot of you have had problems recently with a random update from Java when opening the client. A lot of people cant run the client, and its an easy fix. To fix it, just reinstall the minecraft.jar from the Custom Client download page, and then replace the old minecraft.jar in the "lib" folder of your client, then run. It should work fine now :).

If it doesn't work, you need

If it doesn't work, you need to delete the minecraft.jar, clear your %temp% folders on your computer and clear the Java cache. It works fine.

Wow, this sucks....

Alright guys, to sum this up for ANYBODY who may still be having these problems, I still cannot fix it.  This is what i've tried:

- replacing minecraft.jar in the lib folder
- redownloading the WOM client + minecraft.jar file
- clearing Java cache
- updating Java

It just doesn't work!  Still getting the same error: "Could not find the main class: Main".  Somebody really needs to fix this, like, today.  Thank your for listening to my rant and good luck everyone.

A cache is part of a program

A cache is part of a program that remembers particular settings and parts of a webpage or application, in this case the Java based World of Minecraft application.  Here's a link on how to clear it out:

My problem is, and maybe i'm

My problem is, and maybe i'm just stupid, but you're saying to replace the old .jar in the lib folder of the original client downloaded from minecraft.net but I don't even know where that is. I open minecraft with winrar and theres no lib folder in there, in fact I can't find it anywhere. The only time I ever have a lib folder is from downloading the custom client from this site.

Ok, well now you're in the same place as me.  And just reply to responses; It's a whole lot easier to keep track of messages that way.  Anyways, I'm holding out on somebody to come out with a fix-all solution or for the devs to release a new version of WOM.  I'd say just sit tight for now.

If this fix doesn't work

I can't find another way to fix this; the way you have here doesn't work. This is what worked for me: Follow the directions here, but before you open it, turn off your internet connection. Open it, reenable internet, then hit switch. After that, it should work.

custom client problem

It worked for me thanks! People need to make sure that they delete any of the old minecraft jar files before they download it again.

Hard work never hurt anyone, but why risk it?

Uh, to all you guys who

Uh, to all you guys who couldn't make it work with the above instructions try this one (Windows only, don't ask me anything about mac/linux/whatever):

1. Put minecraft.jar in your lib folder
2. Rename it to something else. (Let's say, minecraft2)
3. Right click on run.bat, click on Edit.
4. Replace all the minecraft.jar you see in the file with the name you put on the jar file in lib folder. (In this case, you would replace with minecraft2.jar)
5. Save it and close, then run the run.bat

It will show the update thing again, but it will access the renamed minecraft.jar instead of the new downloaded one.

When you right click the

When you right click the run.bat file and click edit it will appear a text file. All you need to do is to find on this text file "minecraft.jar" and replace with the name you gave to the jar file in lib folder. 

Then you save it, and it will work
